Water/Meth injection DIY and advice

[ur20v]

Anyone have some pointers on pipe and wiring routing front to back etc on a F10 M5?

I am using the BMS system along with JB4.

Thanks in advance for any tips, photos and advice.

Get a shop to do the work atleast anything goes wrong you hVe something to lean on. Something like this i advice Professional experience

Thanks M5F10Manaul,

I used to be a master tech and have a automotive engineering back ground, so I am more than comfortable doing this and its not a complicated kit, but if others have done the hard yards I am happy to look at options

[NightM]

Got it, i have AEM KIT. best simple meth kit.

F10, any photos of the tank you are using?

Here
5 gallon tank which is what we want instead of 2gallons bigger tank, bigger nozzles
Wire and harness of aem kit are running along the stock harness to give that clean install

[ur20v]

Thanks M5, I have the BMS 2.3 gallon Coolmist tank but have gone and ordered the Aqua mist 5 litre tank for a cleaner install.

How many miles do you get before you burn through 5 gallons?

Depends on your spirited driving. Lol. 1 full day of hard driving. Goes about 1/2 a tank.

F10 is there anyway to know when your tanks is low, or do you just have to keep and eye on it?
I've been thinking of getting meth for my car but I don't know which tune to use with it. How is your setup?

Aem is best for me
Simple to use. Jst gotta keep an eye out. But thats why i have 5 gallon tank. Which holds more than any.


Dme has aquamist and works wonders for him also. So its by preference.

[ur20v]

I changed my Coolmist 2.5 gal tank to twin Aquamist tanks...

Next will be a remote filler and external venting.

I'm looking for an opinion between the Snow Performance kit or Howerton/Aquamist HFS-* kit, which costs 2x as much.

Snow - http://sohiperformance.com/i-2151943...lWxBoCmf3w_wcB
Howerton - http://howertonengineering.com/product/aquamist-hfs-4/

Mind you this will be installed on an X5M without tuning since no one does tuning for meth on my platform yet, so it'll mostly just be for it's carbon cleaning abilities and increased octane to make up for crappy pump gas. I'm just asking you guys because you all have more experience between different kits and if I can get away with simplistic vs wildly programmable when ultimately it'll be highly unlikely I can use either kit to their full potential..

[ur20v]

They are all good kits. The Aquamist is the top of the tree but you pay for this quality and extra features.

I don't think you can go wrong and you will be suprised on the extra performance you get with Water / meth injection without a tune. Atune just takes it to another level.

[m5james]

What are the extra features in the Aquamist setup and how can they help in a situation like mine?

My still lingering question is how the meth controller will control the car. I've read all these threads about how the meth controller can be incorporated into the ECU so that if there's ever a meth flow issue that it'll talk to the ECU to back off boost, timing, etc. I've been told I could install a BMS piggyback ECU and then run the BMS meth kit, but I still don't understand how the BMS piggyback won't interfere with my stage 2 flash tune...not to mention adding $500 to the cost by having to add a piggyback. I'm just curious how that'd work on a car that doesn't have a meth tune and/or that speaks to the ECU. I'm guessing both kits have a fancy controller that'll warn me of flow issues, but I'm also guessing it'll be nothing more than an idiot light in my situation or is there ANY sort of wiring that can be spliced into my ECU so the two can talk?

[ur20v]

Your ecu will add ignition timing if any is pulled due to knock, fuel quality, heat etc, it will lean out slightly as well. As you aren't adding boost etc its safe, it will work as designed adapting to water/meth or not as required.

[m5james]

I've read comments about adding just water will increase compression but somehow still decrease power. I just wanna know the carbon deposits are being cleaned off, no reductions in power, but at the same time adding power would be a perk until someone offers tuning for it on my platform. I've written Snow and Aquamist directly to get their .02 and see who can sell me on their provided information as to which kit is better than the other for my situation.

[ur20v]

Water will add power by controlling knock / ignition pulls and decreasing IAT's and air density.

I have completed 3 BMS JB4 methanol builds for the M5/M6 platform so far.
All builds we only install as close to a factory OEM look as possible. Everything routed as clean and hidden and protected as possible.
Here are 2 images of the methanol tank setups.
1 client wanted a larger tank and didn't care about trunk space and the other image the client wanted a smaller diameter tank.
Both we installed with quick release fittings so the tank can always be removed without the issue of fluid loss or spilling.
Both tanks can be filled in the car without removing the tank.
We routed the protected lines thru the car under the carpet in a very clean install fashion.

If you intend on adding boost based on spraying meth, you can use the Failsafe wiring that's included with this Kit. I have the Aquamist Kit tied directly to my DME and running independently from the tune and the jb4 as I run a stacked setup on my M5. I also use the Howerton tank setup and love the pairing of Aquamist and Howerton.

X5M doesn't have MAF sensors and I can't use JB* or BCM on E70/E71 vehicles, so the only way I can add boost is via flash tuning. I'm just trying to decide if the 2x as much Aquamist kit is even needed based on my platform.

Seems the consensus is that quick release fittings are always garbage over the long-term, no?

Never had an issue myself.
I am fortunate that we have a professional line and fitting company in town called TopLine
They have the best parts and everything is tested and rated for a specific application.
We have a methanol kit installed on a E46 for example that was built 10 years ago and still never had 1 issue with lines or fittings to this day.
Its all in the product quality. There are good and cheap parts...and we all know how that saying goes.
